Brakes 'Sticking'!
I just get in the next day to drive on the way to work, and noticed the brake lights were still on after I got out to turn off the car. Well, I got back in to make sure it wasnt that switch that activates the lights up under the brake pedel. When I get in and start the motor, and press the brakes all the way, they stay stuck, and I have to PULL the pedel back up..and there is a little up movement when I do so, and the lights go out. But it doesnt do it when you have the car off..You can press as hard as you can, they wont stick...Its just while the motor is running. Sometimes after you pull-up the pedel, and apply the bakes again, theres a little stifness, then when you hit it again its normal...But the car stops fine, and the brake fluid levels are ok, and no leaks from the master.
Bad wheel cylinder, or master? Its rear wheel drive..81' olds Delta 88' I told yall I had the collision with from a prior post (everything has been taken care of on that thank GAWD!). Ive had a master cylinder go out before..And the pedel goes to the floor, plus the brake light comes 'on'... This time niether happens. It stops normal

Ok,heres what we just did.... We disconnected the vacume-line that goes to the brake-booster, and the lights go on and off normally. Man, if thats a tricky job replaceing that thing..Because my dad replaced it on his 67' Galexy 500.

I had the exact same thing happen many years ago on a GM I owned; you've got a bad power brake booster. Make sure there is a functioning check valve in the vac line since a backfire can cause failure of the booster as well as gas fumes getting into it.
